COUNTING ATTACHMENT FOR PRINTING PRESSES.

Application filed June 23, 1922. ,Serial at. 570,486.

To all whom it may concern. i

Be it known that I, JOHN DAVID H NT, a subject of the King of GreatBritain, of the city of Toronto, county of York, Province 5 of Ontario,Canada, have inventedlcertain new and useful Improvements in CountingAttachments for Printing Presses, of which the following is aspecification. My invention relates to improvements in countingattachments for printing presses, and one object of my invention istoprovide a counting attachment for that type of printing press which hasa horizontally moving bed which carries the type forms and the chasetherefor, and which will only count when the machine is actuallyprinting. Another object of my invention is to carry away from themachine the printed matter by means of a conveyor, which conveyor willbe prevented fromoperating when the counting mechanism is not inoperation, that is to say, when the machine is not printing, and in thefollowing specification I shall show a disclosure within myinvention,and what I claim as new will be set forth in the claims forming part ofthis specification.

Fig. 1 is a plan view ofthe major portion of a well-known form ofhorizontal printing press, showing my counting attachment associatedtherewith. Fig. 2 is a side elevationof the parts shown in Fig. 1. Fig;2'. is a side elevation of means which controls the operation of thehorizontal conveyor. Fig. 3 is a horizontal cross-section on the line 38 Fig. 1.. Fig. 3 is a'vertical crosssection on the line 3-3, Fig. 2.Fig. 4 is a vertical longitudinal section on the line 4cl, Fig. 1. Fig.5 is an elevation of one side of the rear end of the machine showing theoperating means for the horizontal conveyor, the action of which iscontrolled;

by the counting attachment, and Figs. 6, 7 and 8 are vertical sectionsthrough the bed showing diagrammatically various relative positions ofthe operating rod and bail-post roller.

In the drawings, like characters of reference refer to the same parts. i

The type ofmachineI show my counting attachment associated with iswellknown, and is one wherein the printing cyl-' inder A is .journalledin dolly boxes B mounted at each side of the bed C on the frame of themachine, and these dolly boxes pivotally support the paper-feed bail Dwhich is associated with upper and lower J 6 which is provided with aslot 7 whereby this latch is mounted on a pin 8 carried by the bracket 9which in'turn is suitably supported by the 7 frame of the machine.Mounted to operate longitudinally of the machine is the operating rod 10which is coupled 'byca spring 11 at one end to the frame of the machine.Pivoted at one end of the machine to the frame is the lock-latch12'which is provided with a stud 13 which (Jo-acts with the latch 6. 14is the bumper block carried by the bed of themachine and having the fullrange of movement of this bed. Coupled to the paper-feed bail D, in theusual way, is the feed-bail post 15, and j'ournalled on a stud carriedby the bail post 15 is the bail-post roller 16. The paper-feed bail D ispivoted in the usual way to the dolly boxes B, as shown at 17 and 17(Figs. 2 and 3),.and the pivoting means 17 extends through the feed-bailpost 15 shown in these figures.

The operating rod 10 is provided with a slot 18 into which the bail-postroller 16 must pass before the machine will print. See Figs. 3 and 7.

Suitablv secured to one end of the paper" feed bail D is a post 19,through the $1013 20 of which passes a coupling block 21 flanged atoneend asIshown at 22 to hold it in cooperative relationship with the post19. 23 is a bell-crank lever pivoted at 24 to the post 25 which post issecured to one of the dolly boxe B (see Fig. 3). The post 25 is adapt edto support the counting device 26, the lever 27 of which is coupled toone end of the bell-orank lever 23 by means of a suitable flexiblecoupling 28; The upper end of the bell-crank lever 23 is coupled bymeans of the screw 29 to the coupling block 21, which block of coursehas movement within the slot 20. Now the bail-post roller 16 is in theslot 18 when the parts are in the position shown in Figs. 2, 3, 4 and 7,and the result is that the tilting of this paper-feed bail has thrownthe post 19 to the rights hand, thus through the co-action of thebellcrank lever 23 therewith, depressing lever 27 to actuate thecounting device 26. It is wellknown in the art that the paper-feed bailD is under spring control so as to be moved into the position shown in Fig12 when the slot 18 is brought underneath the bail-post roller 16through the movement of the operating rod 10 when the machinejisprinting. After the machine has printed, the operating rod 10 movesthe'slot 18 which through the medium of its tapered side a lifts thebail-post roller 16 which eventually rides upon the operating rod 10as'shown in Fig. 8. As this bail-post roller 161s lifted, the paperfeedbail D is tilted around its pivotal points 17 'andl7, and the result isthat the post 19 is moved to the left in Fig. 2 thus moving thebell-crank lever 23 around its pivotal point 24, sothat'when thebail-post roller 16 drops into thei lot lSfthe counting device will beagain'actuated. The horizontal conveyor 30 operates around a pair ofrollers 31, one only of which is shown, and these rollers are mounted onspindle 32 which are journalledin the side members of aframe 33supported by, a'pjair of brackets 34 carried by the machine frame. 35 isa ratchet-wheel mounted on and coupled to the spindle 32 shown in Fig,1, and mounted on thisspindle adj acentsaid ratchet-wheel is a lever 36to the upper end of which is pivoted a pawl 37 which normally co-actswith the ratchet-wheel 35,. Loosely mountedon the spindle 32 is-a cam Ilever 38 which is positioned between the ratchet-wheel 35 and a collar39 keyed to said spindle 32. The lever 36 is coupled to an arm-40 (keyedto the driven shaft41) by means of the link 42. As the shaft 41 isrotated, the arm 40 operates the link 42, which link in turn rocks thelever 36 on the spine dle 32, and through the co-ac'tion ofthe pawl 37with the ratchet-wheel 35, operates the conveyor 30.

Now since the post 19 is coupled to the cam lever 38 by a rod 43, andsince this cam lever is overhung by the nose of the pawl 37, it will beunderstood upon referring particularly to Fig; 2 that when the rod 43 ismoved in the direction indicated byarrow throughthe movementto theleft-hand of the post 19.. that the cam lever 38 will contact with thepawl 37 and move it outof engagement with the ratchetwheel 35., and

. thus, although the lever 36 maycontinue to move, preventthe movementof the horizontal conveyor 30. Whenthe post 19 is moved to actuate thecounting device 26, the rod 43 will be moved to move the cam lever 38out of contact with the pawl 37 and thus permit this pawl to co-act withthe ratchetwheel 35 for the purpose before set forth.

There is no necessity of going into the coaction between the lock latch12 and the operating rodlO, latch 6 and bumper block 14 in preventingthe bail post roller 16 from dropping into the slot18 when the machineis not printing because this is wellknown in the art. 7

It is also well-known in the art that some means must be employed tolift the paperfeeler'I out of the path of movement of .the paper as itis fed to the feed rollers E and F Such means is generally indicated inFigs. land 2; and the same comprises a release lever 44 pivoted at '45to" the block 46, which block is carried by the machine frame. Thisrelease lever 44 is controlled in one di' rection of its movement by aspring 47, and in the'other direction by means of a roller 48'pivoted inthe upper part thereof and adjacent one side of the block 46. In theposition shown of the parts in Fig.2, the

roller 48 has been raised up by the passing thereunder of the bumperblock 14. When 'th'eib'ed' moves to the left-hand in Fig. 2,

this bumper'block passes from under the roller 48 thus permitting thespring 47 to move the release lever 44'to the right and bringing it incontact with the arm 4 so as to lift the paper-feeler I.

The conveyor which receives the printed matter as it' issues from thepress is wellknown and is generally indicated by the numeral 50. Theconveyor of course conveys the printed matter to the horizontal conveyor30.

What Iclaim is:

l. Ina machine of the class described, the combination with alpaper-feedbail, feeding and printing'inechanism associated therewith; meanswhereby said paper-feed bail is, pivotally mounted; means co acting withsaid bail to dominate the movements thereof; afirst conveyor, and asecond conveyor embracing a ratchet-wheel provided spindle, of acounting device, means intermediate said counting" device and saidpaper-feed bail 'whereby'said counting device isactudle'of said secondconveyor; a pawl carried thereby to co-act' with said ratchet-wheel; a

cam lever mounted on'said spindle, and a rod connectlng said cam leverwith said means intermediate said paper-feed bail and said countingdevi'ce, the whole adapted to co-operate; as set forth; I

2. In a machine of the class described, the

combinationwith'a paper-feed bail; feed.-

ing and printing mechanism associated therewith, means whereby saidpaper-feed bail is pivotally mounted, and means co-acting with said bailto dominate the movements thereof, of a counting device, sup- 5 portedby the frame of said machine; a slotted post carried by said paper-feedbail; a coupling block mounted in the slot of said post; a bell-cranklever pivoted to the supporting means for said counting device, andpivotally coupled at one end to said block, 19 and at the other endflexibly coupled to said counting device.
